According to one aspect of the disclosure, a bulk material handling method includes receiving bulk material on a first level of a system at receiving stations equipped with dust control filtration equipment, pneumatically conveying the bulk material up to a third level into bulk material storage hoppers, storing the bulk material, dispensing the stored bulk material to a bulk material transporter on the first level, including dosing the stored bulk material to an interior of a bulk material dosing hopper to create a bulk material dose, docking the dosing hopper with the transporter via a docking apparatus, and releasing the dose into the interior of the transporter, through a reduced pressure region in an internal volume of the docking apparatus. Other disclosed aspects include a related system, subsystems, and apparatuses.

Filter arrangements comprising a plurality of radially arranged filters, each filter comprising a plurality of arms, each arm comprising a hollow tube having porous side wall, each hollow tube having an open first end and an open second end, and a tube inner fluid channel having an inner diameter; the filter further including a first tube connector, comprising a first hollow body having porous side walls and a first hollow body inner diameter, connected to, and in fluid communication with, the hollow tubes, and a second tube connector, comprising a second hollow body having a second hollow body inner diameter, connected to, and in fluid communication with, the first hollow body, and filter devices including filter arrangements, and methods of use are disclosed.

Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.
